HELP PLS HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer: C.
Step-by-step explanation:
All we need to do is add all the number together:
Convert to decimals for easier adding:
2.5+2.5+(3.5*5)+4.25+4.25+5.5=36.50km
Now we convert to a fraction: 36.50=36 2/4km
So the answer is 36 2/4km

Answer:
To find the answer, you must multiply/divide the amount in cups by calories per cup.
Step-by-step explanation:
Butter only has 0.3 cups, so The calories will only be 30% of what is written down. 30% of 1627= 488.1 calories
Marshmallows is 4.25 times larger then the calories per cup, so now you'll have to multiply.
4.25*159=675.75 calories
Finally, Cereal is 5.5 times larger then the calories per cup, so we will multiply again.
5.5*101=555.5 calories
Finally, add all the number together to find the total amount of calories in the marshmallow treats.
555.5+675.75+488.1=1,719.35 calories
There is a total of 1,719.35 calories in the marshmallow treats.

1 + x < 5
the sum means addition, so the sum of 1 and x is 1 + x and less than 5 means exactly that, less than 5. The less than sign is represented by <
The statement "the sum of 1 and x is less than 5"written as an inequality is 1 + x < 5.
x < 4
How to write inequality?An inequality is a statement that is of two quantities one is specifically less than (or greater than) another.
The sum of 1 and x is less than 5
1 + x < 5
Subtract 1 from both sides
x < 5 - 1
x < 4
Therefore, x is less than 4

An auditorium has three levels. Level 1 seats 3,577 people, Level 2 seats 5,214 people, and Level 3 seats 5,879 people. How many seats are in all three levels combined? A. 8,991 B. 14,670 C. 14,970 D. 14,370
3577+5214+5879
=8791+5879
=14670
Answer
B. 14,670
The total number of seats in all three levels of the auditorium is calculated by adding the number of seats on each level, resulting in 14,670 seats.
To calculate the total number of seats in all three levels of the auditorium, we add the number of seats available on each level together. The calculation is as follows:
Level 1: 3,577 seats
Level 2: 5,214 seats
Level 3: 5,879 seats
Add these numbers to get the total:
3,577 + 5,214 + 5,879 = 14,670 seats
Therefore, the correct answer is B. 14,670, which is the combined number of seats in all three levels of the auditorium.
A group of art students are painting a mural on a walls the rectangular wall has dimensions of (6x+7) by (8x+5) and they are planning the mural to be (x+4) by(2x+5). What is the area of the remaining wall after the mural has been painted
Answer:
46x^2 + 73x + 15
Step-by-step explanation:
Expand both equations
Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35
Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20
Minus them.
Wall - Mural =
(48x^2 + 86x + 35) - (2x^2 + 13x + 20)
(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)
46x^2 + 73x + 15
Answer:
46x^2 + 73x + 15
Step-by-step explanation:
Expand both equations
Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35
Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20
Minus them.
Wall - Mural =
(48x^2 + 86x + 35) - (2x^2 + 13x + 20)
(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)
46x^2 + 73x + 15

Answer:
ON MONDAY: 35 mosquitos.
ON TUESDAY: 6 flies.
Step-by-step explanation:
As you can see in the diagram, the frog eats 3 flies for every 7 mosquitoes (for lunch). Then you can expresed this ratio as following:

Answer:
JMK = 54
JKH = 126
HLK = 90
HJL = 27
LHK = 63
JLK = 27
Step-by-step explanation:
Just use 180 for total angles in each triangle. Vertical angles mean the opposite to 126 is 126 and the other two that make up the inner vertices are (360- 126*2)/2 = 54
So, 126, `16, 54 , 54 are the inner angles in the circle. Just go from there.

Find the radius of a circle with a circumference of 35 π yards
Answer:
17.5 yds because Radius is half of the circumference
Step-by-step explanation:
The radius of the circle with a circumference of 35 π yards is 17.5 yards.
Circumference of a circle:The circumference of a circle is the perimeter of a circle. Therefore,
circumference = 2πrwhere
r =radius
Therefore,
circumference = 35πyard
35π = 2πr
divide both sides by 2π
35π / 2π = 2πr / 2π
r = 17.5 yards

To evaluate the expression, we follow the order of operations (PEMDAS). The result of the expression is 31.
Explanation:To evaluate the expression 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2, we need to follow the order of operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, we perform the division: 24 ÷ 3 = 8.Next, we perform the multiplication: 7 ⋅ 2 = 14 and 6 ⋅ 2 = 12.Now, we can write the expression with the values we found: 8 + 14 - 15 ÷ 5 + 12.Then, we perform the division: 15 ÷ 5 = 3.Finally, we perform the addition and subtraction from left to right: 8 + 14 - 3 + 12 = 31.Therefore, the evaluated expression is equal to 31.

Which graph represents an exponential function?
Answer:
The first graph.
Step-by-step explanation:
An exponential function has a graph that is a smooth curve; it either increases at an ever increasing rate or decreases at an ever increasing rate.
The only graph that fits these characteristics is the first one.
Answer:
First graph is the exponential function
Step-by-step explanation:
The x value of exponential function is all real numbers
x can take any value positive or negative numbers
In the first graph , as x value increases the graph goes down
The first graph is an exponential function .
Second graph is the cubic function as the graph goes from left and it goes down on the right .
Third graph is an rational function because we have two graph on both sides of vertical asymptote
The fourth graph is not an exponential function as the domain is not all real numbers.

What is the value of the expression below? (4/5+3/5)+3.5*5
Step-by-step explanation:
(4/5+3/5)+3.5*5
= 7/5+7/2*5
= 7/5+35/2
= 14/10+175/10
= 189/10
= 18.9
Answer:
The value of the expression is 18.9
Step-by-step explanation:
The expression is:
[tex]\bigg( \frac{4}{5}+\frac{3}{5}\bigg)+3.5\times 5[/tex]
The first step is to solve the parenthesis. As both fractions have the same denominator, the numerators must be added:
[tex]\bigg( \frac{4+3}{5}\bigg)+3.5\times 5[/tex]
[tex]\bigg( \frac{7}{5}\bigg)+3.5\times 5[/tex]
The second step is to perform the division between 7 and 5, it is 1.4:
[tex]1.4+3.5\times 5[/tex]
The third step is to perform the multiplication between 3.5 and 5, it is 17.5:

The total surface area for the given prism is 808 square inches.
The question asks to calculate the surface area of a rectangular prism in square inches. The dimensions given are 1 1/2 ft (length), 2/3 ft (width), and 5/6 ft (height). To convert these measurements to inches, we multiply by 12 since there are 12 inches in a foot. Thus, the dimensions in inches are:
Length: 1 1/2 ft x 12 = 18 inchesWidth: 2/3 ft x 12 = 8 inchesHeight: 5/6 ft x 12 = 10 inchesTo find the surface area, we calculate the area of each face and then sum them:
Area of the front/back faces: Length x Height = 18 inches x 10 inches = 180 square inches (two faces, so 2 x 180 = 360 square inches)Area of the top/bottom faces: Length x Width = 18 inches x 8 inches = 144 square inches (two faces, so 2 x 144 = 288 square inches)Area of the side faces: Width x Height = 8 inches x 10 inches = 80 square inches (two faces, so 2 x 80 = 160 square inches)Now, add up all the areas of the faces to get the total surface area:
Surface Area = 360 + 288 + 160 = 808 square inches.
